nLIGHT IncDefense revenue mix grew from 18% to 70% of sales, with 60% YoY growth in fiscal 2025, driven by U.S. Department of War priorities in directed energy.

Prosper Stars & Stripes exited its position in nLIGHT in early April after the stock hit its price target, the fund said in its first-quarter 2026 investor letter. nLIGHT was the second-largest contributor to the long book during the quarter, benefiting from a defense revenue mix that has grown from 18% of sales in fiscal 2018 to 70% today. The company's defense segment delivered 60% year-over-year growth in fiscal 2025, supported by U.S. Department of War priorities in directed energy and limited competition in coherent beam combination technology. The fund initiated the position in May 2025 and cited nLIGHT's vertical integration, more than 450 patents, and a 300-kilowatt-class high-energy laser demonstration under the HELSI program as key differentiators. The portfolio overall returned negative 5.6% net in the first quarter, underperforming the Russell 2000 Index's positive 0.9% return.
